Stacie has posted regular updates on social media documenting changes in her body.

She didn’t show until 20 weeks, when her jeans began to get tight, and by 25 weeks she admitted some routines, such as yoga, were getting more difficult so she adjusted her workouts to include more core training.

She said doctors say the baby is doing well:

She added: “Don’t let someone else’s negativity ruin your day or even stress you out during your own pregnancy.

“One person may gain 15 pounds and the next may gain 100 pounds; everyone is different. You can only compare yourself to who you were yesterday.”
